About 30 firefighters toiled throughout the day to control the fire, the third in Waianae Valley this week, and a fire helicopter made water drops before operations were ended about 6 p.m., said Honolulu fire Capt. Terry Seelig.

He said the fire near Piliuka Place burned sideways along a mountain valley wall on Friday and didn't burned towards the foot of the mountain, where it would have threatened property. The cause of the fire was undetermined.

Some 60 firefighters responded after the fire started about 3 p.m. Thursday and prevented it from reaching about 8 houses or farm lots near Piliuka Place, Seelig said.

The other major fire began Monday afternoon at Radford Street and Kolekole Road on Naval Magazine Lualualei and had consumed nearly 1,200 acres. It spread into the areas bordering the Waianae Kai Forest Reserve.

Cleanup operation in Lualualei is being done by federal and state firefighters.

Federal firefighters contained 98 percent of the fire on Lualualei by this afternoon, said Agnes Tauyan, Navy spokeswoman.

The same fire burned about 400 acres in the Waianae Kai Forest Reserve, and state firefighters contained 75 percent of that area by Friday, said Deborah Ward, spokeswoman for the Department of Land and Natural Resources.

Seelig said Thursday's fire is unrelated to Monday's Lua­lua­lei fire or a 3-acre brush fire that burned near Piliuka Place on Wednesday. The cause of Wednesday's fire was undetermined.
